Fun Facts About the Sun Video
This Easy to understand video tells a lot of amazing facts about the Sun.
The Sun is the star at the centre of our solar system and is responsible for the earth’s climate and weather. It is an almost perfect sphere with a difference of just 10 km in diameter between the poles and the equator. The average radius of the Sun is 695, 508 km of which 20-25% is core. It is a big star. At about 864,000 miles wide, it could hold 109 Earths across its surface. If the Sun were a hollow ball, more than a million earths could stuff inside it. But the Sun is not hollow. It is filled with scorching hot gases that account for more than 99.8 percent of the total mass in the solar system. Deep in the Sun’s core, nuclear fusion reactions convert hydrogen to helium, through which energy is generated. Particles of light, called photons carry this energy through the Sun’s spherical shell, which is called as radiative zone, to the top layer of the solar interior, the convection zone. There, boiling motions of gases transfer the energy to the surface. This journey takes more than a million years.
Quick facts: –
- At its centre, it reaches temperature of 15 million °C.
